React Component Performance Overview Identify render hotspots, isolate expensive updates, and apply targeted optimizations without changing UI behavior. Workflow 1. Reproduce or describe the slowdown. 2. Identify what triggers re-renders (state updates, props churn, effects). 3. Isolate fast-changing state from heavy subtrees. 4. Stabilize props and handlers; memoize where it pays off. 5. Reduce expensive work (computation, DOM size, list length). 6. Validate : open React DevTools Profiler → record the interaction → inspect the Flamegraph for components rendering longer than 16 ms → compare a…
